It was more about filling contracted orders. AT&T had VT229 tube contracts filled by Sylvania and the boxes state as much but some believe the tubes were produced by AT&T. So it goes.
There were many exceptions like the 596 rectifier, Bendix Red Bank tubes etc. but most were just cranked out in volume. Normal good quality stuff.
